I just returned from the dealership… Had them look at this issue as well as perform some software updates… They checked with Chrysler and was told the sound is normal for 4x4's... Something about the transfer case continuously trying to optimize something… anyhow, it really isn't that loud and now that I know there is nothing wrong, I am happy.

I have a new 6-19-14 bod jgc, and thx to this, and the other thread I have this rotational clicking as well. so hopefully everybody has this, and it's just not that noticeable and hopefully normal. I know I had no idea before I saw this thread of the issue/sound, and I would like to think I'm pretty good at unusual sounds coming from my vehicles.
